Depends i spose on how serious the class gets....I have always thought about a class where you race people based on times that are with in 5 odd seconds of each other....any size plane,mtr,race what you like.

Chris or any1 else...can we get the 'limited f5d rules' set in stone?So will we be following/useing "Germany regulations"...the only difference being-850g minimum/500w minute (limiters apply)....is that the go ya reckon? Any other rules..?

The Germans run F5D Lite as their feeder class, which is max 3S, 800 g min weight and 450 W/min energy limit. The flying is essentially the same as F5D. They do 1:20-1:30s. Most use F5D airframes, but, F5D itself is pretty open airframe wise (Max 65g dm2 is the only real rule), its not highly restricted like Q500 etc.

The NZ sports class has essentially been ratified as ( I wouldnt expect it to change )

850g minimum weight500W static, at 60% charged packs.

Models do not require an undercarriage (But feel free to put one on and get your ass lapped!)Must be tractor motor2 bladed propConventional configuration with front wing and rear stabilizers, V tails allowed.

So the rules are not really similar, BUT, both are very open. F5D lite is much less easy to fudge the power limits with the energy limiter.

If you bring a plane along, it weighs more than 850g, and pulls less than 500W static, it'll race

Ive used it in both, its faster in the avionik obviously, but hauled the wasp around well. Did 1:30's with the wasp (when I was really new at it), I did a 1.21 with the avionik using it (with 5 close cuts, and some wobbly lines) the other day. Its definetly fast enough and fits the rules.
